I've tried agility, flyball and heel work to music with my older dog. I wanted to see which suited us best. Flyball was a no-no - he kept running away with the ball during training much to everyones disgust - heel work to music worked really well for teaching him tricks and keeping his attention on me, but I think we both prefer agility. I think he likes it that I have to work too and the exercise is good for me.
